    <p>JpGraph library is an OO graph library which makes it easy to both draw a "quick and
        dirty" graph with a minimum of code and quite complex graphs which requires a very fine
        grain of control. The library tries to assign sensible default values for most parameters
        hence making the learning curve quite flat since for most of the time very few commands are
        required to draw graphs with a pleasing esthetic look.</p>
    <p>The following list makes no claim to be complete but it will give a birds view of some of
        the main (and in some cases unique) features of the library. The list will also illustrate
        the difference between the free and the pro-version.</p>
